Abstract
In producing a copper concentrate by flotation in which copper minerals are separated from arsenic minerals by using oxoacids of sulfur and oxidants, the arsenic in the copper concentrate is reduced by a simple method. In producing the copper concentrate by the flotation in which an arsenic-containing copper ore is a raw material, the oxoacids of sulfur and hydrogen peroxide as the oxidant are used together as additive reagents, and added in this order.
